ENTSOG Implementation and Effect Monitoring Report 2017 - Congestion Management Procedures Guidelines

Effect Monitoring Indicators

CMP INDICATORS

Effect monitoring will be performed only on the side of IPs considered to be congested by ACER in its latest annual report, published 31 May 2017 concerning contractual congestion at interconnection points.

ENTSOG has decided to develop the following indicators.

Indicator 1 (CMP.1): Additional capacity volumes made available through each CMP

The “x” in CMPx is to be replaced with one the following num- bers, depending on the CMP measure it was calculated for:

Note: If the amount of unused capacity reallocated by TSOs to the market at network points measures the effectiveness of CMP, an analysis and overview of congested IPs will be also needed to gain a deeper understanding of the situation at each IP.

\\ 1 for Oversubscription and Buy-Back

\\ 2 for Firm Day-Ahead UIOLI

\\ 3 for Surrender of Contracted Capacity

Premise 1: gas year to be used is from 1 Oct 2016 to 30 Sep 2017

\\ 4 for Long-term UIOLI

Indicator 2 (CMP.2): Share of capacity reallocated through CMP among total capacity reallocated

Premise 2: MWh/h/y is used as the unit for every product to monitor the evolution of the below mentioned ratio by gas year for every of the 4 CMP tools.

Calculation formula:

Calculation formula:

CMP2 =   ACMP   × 100 (ACMP+ASM)

CMP1 =   ACMPx   × 100 CMPx

Where:

Where:

CMPx:

Return ratio of additional capacity allocated through a given CMP relative to the total allocation of addi- tional capacity within a definite period of time.

CMPx:

Return ratio of additional capacity allocated through a given CMP measure, relative to the total addition- al capacity offered through the given CMP measure.

ACMP: Sum of allocated additional capacity offered through CMP measures within a definite period of time.

ACMP: Sum of additional capacity allocated through a given CMP measure.

ASM:

Sum of allocated capacity acquired from organized secondary markets within the same period.

CMP:

Sum of additional capacity offered through a given CMP measure.

Interpretation:

Interpretation:

CMPx = 100: all reallocated capacity is supplied through CMP measures applied by TSOs

CMPx = 100: All of the additional capacity offered through the CMP measure has actually been allocated, indicating a fully efficient CMP measure where the market demand for this additional capacity is allocated through the CMP and fully acquired by market parties. CMPx < 100: indicates that the allocated percent of addition- al capacity offered through each CMP measure is efficient, even though the market demand was less than supply for of this additional ca- pacity during the period under consideration.

CMPx < 100: This indicates that network users reallocate ca- pacity themselves using the secondary market and not only through CMP measures applied by TSOs

Conclusion:

The higher the CMPx, the better the acceptance for addition- al capacity offered by applying CMP measures compared to using the secondary market. The lower the ratio, the higher the capacity that is allocated on the secondary market in comparison to offer via the application of CMP measures.
